INTRODUCTIONC-1.Generala.This section provides a general explanationof all maintenance and repair functions authorized atvarious maintenance levels.b.Section II designates overall responsibilityfor the performance of maintenance functions on theidentified end item or component and the work measure-ment time required to perform the functions by thedesignated maintenance level. The implementation ofthe maintenance functions upon the end item orcomponent will be consistent with the assignedmaintenance functions.c.Section III lists the tools and test equipmentrequired for each maintenance function as referencedfrom Section II. Not Applicable.C-2.Explanation of Columns in Section IIa.Column 1, Group Number. Column 1 listsgroup numbers to identify related components,assemblies, subassemblies, and modules with the nexthigher assembly. The applicable groups are listed in theMAC in disassembly sequence beginning with the firstgroup removed.b.Column 2, ComponentlAssembly. Thiscolumn contains the noun names of components,assemblies, subassemblies and modules for whichmaintenance is authorized.c.Column/Maintenance Functions.Thiscolumn lists the functions to be performed on the itemlisted in column 2. The maintenance functions aredefined as follows:(1)Inspect.To determine serviceability ofan item by comparing its physical, mechanical, and/orelectrical characteristics with established standardsthough examination.(2)Test. To verify serviceability anddetect incipient failure by measuring the mechanical orelectrical characteristics of an item and comparing thosecharacteristics with prescribed standards.(3)Service.Operation requiredperiodically to keep an item in proper operating condition,i.e., to clean(decontaminate), to preserve, to drain, to paint, or toreplenish fuel, lubricants, hydraulic fluids, or compressedair supplies.(4)Adjust. To maintain within prescribedlimits, by bringing into proper or exact position, by settingthe operating characteristics to specified parameters.(5)Align.To adjust specified variableelements of an item to bring about optimum or desiredperformance.(6)Calibrate. To determine and causecorrections to be made or to be adjusted on instrumentsor test measuring and diagnostic equipments used inprecision measurement. Consists of comparison of twoinstruments, one of which is a certified standard ofknown accuracy, to detect and adjust any discrepancy inthe accuracy of the instrument being compared.(7)Install. The act of emplacing, seating,or fixing into position an item, part or module (componentor assembly) in a manner to allow the proper functioningof an equipment or system.(8)Replace. The act of substituting aserviceable like type part, subassembly, or module(component or assembly) for an unserviceablecounterpart.(9)Repair. The application ofmaintenance services (inspect, test, service, adjust,align, calibrate, or replace) or other maintenance actions(welding, grinding, riveting, straightening, facing,remachining or resurfacing) to restore serviceability to anitem by correcting specific damage fault, malfunction, orfailure in a part, subassembly, module (component orassembly), end item, or system.(10) Overhaul. That maintenance effort(service action) necessary to restore an item to acompletely serviceable/operational condition asprescribed by maintenance standards (i.e., DMWR) inappropriate technical publications. Overhaul is normallythe highest degree of maintenance performed by theArmy. Overhaul does not normally return an item to alike new condition.Change 5 C-1
